    PPC7410 thermal adheasive?

    PPC7410 thermal adheasive?

    This isnt really mac related, but its the same CPU. I have a single board computer that once had a little snap clip heatsink that hugged the CPU itself, and the heatsink part screwed on. Kinda neat. But it broke.... Cant seem to find that thing anywhere, and I was wondering if anyone has any experience with the PPC7410 chip or know if a thermal glue/adhesive would work on this type of chip?
  4. Thats funny. ive seen them on both sides. Maybe different board revisions were different? Edit: I had to go back and look at the photos. Yea that board version has the cutouts only on one side. Strange! ive seen it on both. So they must have had different board versions over the years.
  5. I see your cut-out borders on one side, but its missing the cutout completely on the PDS side? is this intentional? just curious.
  6. The PCB is cracked. you need to find the fracture in the PCB, and make bodge wires to reconnect the broken traces.

    Repair a 15" Multiscan

    Ive ran into this problem in the past. There is a transistor that goes bad on a little tiny daughter card style PCB thats mounted on a heatsink in the rear of the monitor. You should check this. (Im going from memory, dating back to 2000, so it can be fuzzy)
  8. You have an x-ray machine handy? Yea.....

    After reading this thread, I cant seem to find anywhere that tells me "how" they are bad. Basically, what are they doing/not doing?
  10. This is one hell of a challange, and if I were to have done this, my approach would have been alot more involved and difficult. I dont know how you can take a photo and convert it back into electrical connections again, but I would have done what I know to do, and thats built a netlist of all the connections of the board, reverse it back into a schematic and layed out a new PCB from there. Anyways, seems your method is much easier. haha. Also, id love for this to be done with the SE/30. I have a pile of those boards dead and screwed from battery juice. Be forewarned, the SE/30 has traces that run in the middle layers as I saw, and I am not sure how your approach would be for that.

    Issues with Mac SE/30 display (and more?)

    That looks like a bad connection on the Yoke, or the yoke itself is bad.

    SE/30 analogue board fun

    ive used rejuvenation many times in the past with TVs and other things, it doesnt last. Its a temporary thing, because what it does is blow off the oxides of the cathode material on the CRT itself, but with it you lose a bit more emissive cathode material. Eventually it will fade in short order and youll lose the CRT entirely. Its good enough to boost a little life out of it, but once it reaches that point its basically the end of the road for that CRT.

    Macintosh SE/30 Restoration

    if all the lines check out, then it is likely a bad IC. Youll probably need to locate a donor board that uses the same apple sound chip, its probably easier to get your hands on a board that has a blown up battery or something and use that for parts.

    Or its a weak CRT. it can happen.
